forKeys, the reader can identify its corresponding key directly from the name, but forAxes, and it corresponds toKeysthe reader may not understand it, and the reader might sometimes need to modifyAxescorresponding to theKeys, sometimes it is added directlyAxes. Well, inUnityHow to add and modifyAxesit? Method is, clickedit| Project settings| Inputcommand, you can bring up a popup namedInputManagerdialog box in which the reader can add and modifyAxes,1-10is shownThis article is selected fromNgui from introductory to actual combat tutorials.
